Specification of Letters Patent.

Patented Apr. 12, 1921.

Application filed October 17, 1917. Serial No. 197,065.

To (all 71272-0771: it may concern Be it lrnown that I, IIENRY KINssronn I'IARRIS, a subject of the, King of Great Britain and Ireland, residing at 96 Victoria street, V'i estminster, in the county of London, England. have invented certain new and useful Improvements in Electrical 'lransmitting Apparatus, of which the following is a specification.

This invention relates to electrical transmitting apparatus of the hand set type, manipulated by hand. or power for trans mitting electrical impulses to an advertising or other device adapted to be set into position by such electrical impulses, and combined, if desired, with automatic means for reversing the direction of movement of the device to be set into position.

The apparatus about to be described, wiile being applicable to the control oi many types of electrical devices is particularly suitable for controlling advertising devices and selectors for advertising devices, that is to say tor controlling the position oi an advertising part or indicating iart directly, or through the intervention of a selector, which can be set either through unit or through both unit and multiple step distances for controlling the position of the indicating part.

The objects of the apparatus are to enable the controlled device to be set into any desired position with great facility and. to eliminate the chance of errors when an unskilled operator is effecting the setting.

The apparatus is adapted for use with an advertising or indicating device in which the part hearing or controlling the indication, for instance a band, is moved in either direction so as to proceed directly from one indication to the next, the calculation of the distance being in that case effected in the transmitting mechanism, and means being provided automatically operated from the transmitting mechanism for causing iiilfi part to be set to move in the correct direc-' ticn, or again the transmitter may be used in combination with a self calculating selector, such for instance as the kinds described in specifications of my former patent, in

which case the calculation and direction of setting need not be effected or controlled in the transmitter.

For use with a single and multiple step selector oithe character described in my former specifications Ser. Nos.8l6,730 and 186,207 I so modify the construction of the transmitter that itis adapted to transmit automatically the proper impulse or impulses for operating the unit step part and the multiple step part. or parts in the selector. I

The self calculating form of the transmitter comprises a moving member, means controlled by the moving member for transmitting a number of electrical impulses, according to the distance through which the said member is moved, anindex on the moving'member or on the casing, or adjacent to one of them, adjustable means in connection with the moving member or the casing for determining and limiting the distance through which the said member is to move in proceeding from one setting to the next, and automatic means operated by the moving member such that when in determining a setting, the moving member moves in one direction it causes the device to be set, to

movein a certain direction, while when it moves in the opposite direction, the device to be set moves in the reverse direction to that in which it was moving previously.

In a convenient constructional form, the index is provided on a wheel in the casing, a stop or peg is adjusted in position with reference to the index and the stop is brought back against a fixed stop, such as a stop on the casing.

With this form of construction the position of the moving part in the transmitter before each new setting corresponds with the position of the device to be set 1n the indicating unit or equivalent part and the reversing means comes into operation every time the direction of movement of the mov- Signal lights or other indications may be added so that the operator may be able to tell when the steps in the cycle of operations at the indicating machine are complete.

Where several units are provided and no unit switching selector is employed, each unit wheel or the like in the transmitter may be connected to the corresponding unit by the necessary wires.

And in order that my said invention may be more clearly understood I will now proceed to describe the same with referen'ce to the drawings accompanying this specification which show by way of example, various forms of hand set apparatus for transmitting electrical impulses.

In the drawing Figure 1 is a sectional end elevation of one form of the apparatus suitable for sending single step impulses. Fig. 2 is a section on the line 2-2 of Fig. 1. Fig. 3 is a detail of the reversing switch and brush carrying bar. Fig. 4: is a front view of a portion of the device. Figs. 5 to 9 show details hereinafter referred to. Fig. 10 is an elevation of a modified form of construction of transmitting wheels for transmitting single and multiple step impulses. Fig. 11 is a modified arrangement of the index carrying member. Fig. 11 is a front elevation with the casing removed, of a recording apparatus suitable for use with the transmitter. Figs. 12 to 16 are diagrams, illustrating systems of working in conjunction with the transmitting apparatus. Fig. 12 is a detail of the unit setting selector and its magnet.

The same numerals of reference are employed to denote the same parts in all the Provided adjacent to each of the letters i or other signs is a hole into any one of which a clip, pin or its equivalent may be inserted as hereinafter described.

The lower part of the wneel 12 is provided with a rim 13 having teeth of any suitable form produced thereon.

1 1 is a rocking arm pivoted at 15 upon a shaft which is common to all the arms for the wheels 12. One end'16 of this arm carries a roller, which is adapted to engage with the teeth on the rim 13. The other end 16 carries a spring controlled rocking piece which engages with a contact maker 17 which makes contact with the screw 18.

Mounted below the end 16 of the rocking arm 14; is a locking cam, 19 provided with a handle 20. The cam surface is so formed that in one position the device locks all the arms against the rims 13 preventing the wheels 12 and the arms 14: from being moved.

Mounted on the axis of the cam 19 is a wheel 21 which is provided with a notch 22 in which a catch 23 under a spring tension is adapted to engage, when the mechanism is in the free position. The wheel 21 carries a pin 24, between which and some fixed portion of the casing is a tension spring 25. The catch 23 is connected by a wire 26 to a trip 27 which is operated by a pin 28 011 the snail 29, hereafter more fully described.

'60 is a second notch in the wheel 21 with which a locking catch 61 engages, when the cam 19 is in the locking position. The locking catch 61 is lifted by a spring controlled rod 62, which is provided with a roller 63 which is adapted to be lifted by the flexible shutter 6-1 when the same is opened for the purpose of working the machine.

I will now describe the mechanism for operating the setting wheels 12. 31 is a pin adapted to engage in any one of the holes 30, one pin being of course provided for each wheel 12. 32 are radial arms pivotally mounted on the shaft 11. Two similar arms are provided at the other end of the machine and the outer extremities of the corresponding arms at each end are connected by traverse bars 33 in such a way that as the radial arms 32 are rotated about the shaft 11 the traverse bars 33 are caused to travel over the surfaces of the wheels and to come into contact with any pins which are inserted therein, thus pushing the wheels before, them for the remainder of their movement at the same time causing the con tact making arm 14 to be operated by the teeth 13.

As will be clearly seen in Fig. 1 each time a tooth on the rim 13 passes over the roller 16 on the rocking arm 1%, the latter is tilted, causing the spring controlled end 16 to push against the sloping surface on the contact blade 17, bringing the same into contact with the screw 18. As soon as the end of the part 16 passes the end of the sloping surface 17 the blade 17 is released and the circuit suddenly broken. On the return of the arm 14-, the piece 16 is enabled to pass, being tilted upward against the action of its controlling spring.

The arms 32 have attached to them links 34; which at their ends are connected to a sliding piece 35. The sliding piece 35 which runs in guides 36 carries a roller 37, con veniently of hide, which runs upon the surface of the snail 29. A section of the slide is shown atFig. 5. The upper portion of the slide 35 carries a rod 38 having a compression spring around the same and passing through the frame. The snail 29 is fixed to the shaft 11 and also attached to the shaft 11 is the worm wheel 39. Engaging with the worm wheel and carried on a separate shaft 40 is the worm 41. The shaft 40 which passes through the case 10 carries at its outer end a hand winch, 42. This winch 12 on being rotated in a clockwise direction moves the shaft 11 and the snail 29 in the desired direction to operate the setting of the wheels 12. The shaft 10 carries a coiled wire spring 13 one end of which is attached to the supporting frame of the machine and prevents the handle being turned in the wrong direction. When the arms 32 carrying the traverse bars 33 are operated by the mechanism described they bring the two arms simultaneously to a line corresponding to the center of the opening or set-position, at the same time turning the respective wheels 12 in the desired directions to transmit the required nun ber of impulses to the exhibiting station.

Referring to Fig. 2 the hub of each of the wheels 12carries a friction arm 44, only one of which is shown. Eachof these arms is held in position by a threaded collar 15 which screws on to the hub and is held by a lock screw. The frictional arm 1% has mounted upon it and passing through it a spring d6 which gives the necessary tension. The outer end of th arm projects between the rims 13 of the wheels 12 which are suitably cut away for this purpose and engages with a reversing switch 17 the construction of which may be clearly seen in Figs. 1 and 2. This comp *ises an ebonitc drum mounted on a shaft common to a number of such switches carrying contact plates as shown in the Fig. Engaging with these contact plates when in the right position are a; series of four brushes as. These brushes are under suitable spring tension and each of them is carried in a metal tube a9 mounted in an ebonitebar and having.

upon the shaft 11, it carries i ith it the fric tion arm, 14, but that this can only move over a distance of arc'corresponding to one tooth in either direction, and. it therefore remains in the same position with respect to the switch as that into which it was last set, until the same wheel 12 is moved in the opposite angular direction, whereupon the corresponding friction arm is moved over by the wheel reversing the switch and consequently bringing about the reversal of the current as desired, as will be described 40 a notched wheel .54. Engaging with this is a locking catch which is pivoted at 56 on the frame. This catch has pivoted thereto a vertical rod 57, which extends to the bottom of the cas ing, and is pressed normally downward by means of a compression spring 58.

The object of this arrangementis to lock the operating handle out of action when the machine is not in use and this may be effected by its engaging the flexible shutter 64 sliding in the slot 59. This shutter is provided with means adapted to lift the rod 57 against the spring 58, when the shutter is moved in to the open position, thus freeing the handle. In Fig. 1 I have indicated the shutter in dotted lines in open position, the wedge 6 1 which lifts the rod 5'? being shown in full lines. This shutteris substantially the same as those in use for the roll top desks. It may be moved from the dotted line position so that the upper portion of the shutter is at the point 200 in Fig. 1. The purpose of the shutter is to prevent tampering with the machine and to keep out the dust.

A second locking catch may be provided, operated by a solenoid from the exhibiting station, in such a way as to lock the transmitting mechanism when the exhibiting units are being set in a manner already described in connection with some of my aforesaid devices, and indicated in one or more of the diagrams accompanying this specification. In F 8, I have shown the modified form of locking mechanism. It consists of aniron clad magnet 110 having attached toits armature 18. a brass push rod 188 carried by its core so as to slide thereinand protruding at the back so as to pass through a hole in the arms 189. This arm is hinged in a lug 190 attached to the caseof the net and passes between the slotted end of another lug 191 which acts as a guide and takes up the side thrust on the arm should the wheel 5%. which the arm locks be moved.

The rod 188 may carry a compression spring 192. which in the event of the arm 189 not coming exactly opposite a slot in the wheel 54 allows the armature and plunger rodlSB to move into the locking position but should the wheel 5% be moved the arm 189 will inimediately be forced by the spring into the slot which is brought opposite to it. A compression spring mounted on the back of the rod and sunk within the core of the magnet keeps the same normally in the off position.

I will now describe a. device which may be combined with my machine for the purpose of controlling the rest circuits which operate the locking and signaling devices from the indicating station, locking the ing casing is provided. she"). at

transmitter and giving an indicating signal, for instance lighting a red light at the transmitting station to show that no more signals must be transmitted or that the transmitter cannot be operated until the setting is effected at the exhibiting station, when the machine is unlocked from he exhibiting station, and another signal, for instance a green light is shown at the transmitting station indicating that the machine can again be operated.

For eiiecting this purpose, l provide an arm 104-, pivoted at 105 to th casing. This arm is under spring control. (Jlren the snail 29 is in its norm l rest po. tion, the end of this arm rests on pin 28. in his position an insulated p ate which is carried by the arm is pressed against three spring contact studs 106, thus completing the rest circuit; On the other hand when the snail moves forward it causes th pin 28 to allow the arm to drop under the action of its spring breaking the rest ircuit until the snail has completed the cycle of operations.

ll hcn the transmit er has completed its setting cycle, pin conveniently placed on the arm 32 may cause a bell to be sounded, the pin engaging, on its return with trip spring; 108 causing; the bell 109 to be struck.

1'11 some cases instead of using the contact making arm 1 l may use a plunger, as shown at 6 which closes the contact for transmitting the impulses. ln the form oi the wheels shown at l the letters are arranged in order of q11e11cy, with a hole adjacent to each of the letters and there is no casing over the part of the wheels 12 carrying the letters. T his form of the rim is more oecially suitable for purely mechanical setting.

Fig. 7 shows a modified form in which each of the wheels 12 is provided with two sets of holes 80, one hole coming; on either side of each letter. In this instance a coverwi This casing is so shaped that one. letter and the corresponding: holes on each side of it are visible in the central or setting position, while on each side or that position only the holes corresponding to the letters on one side or the other or the settinsr are visible, as will be clearly seen from the figure.

The ob ect of this arrangement, which is suitable for both hand as well as mechanical setting, is that it is impossible to rotate the wheel 12 too far, a the pin 31 comes up against the shoulder on the casing 66, when in the set position.

Referring to 9, this shows a device which may be used in place of the cam 19 and which may be used for locking the wheels and freeing them in succession, where is desired to operate over single in place of multiple lines. In this case is a drum mounted upon a suitable axle 71. This drum is provided with holes 72, which are staggered or come in different positions on the surface. One hole corresponds to each of the contact making devices, such as ll or the rod shown in Fig. 6 and when the corresponding hole comes beneath its rod 73, the particular contact making movementcan be operated, while the others remain locked. It will be noted that the holes on the locking drum are staggered so that only one movement is free at one time.

The drum is rotated by means of pawl 74 engaging with suitable ratchet teeth 75 upon the drum. The pawl is carried by a spring controlled rod provided with a push button 76. ln this way the drum can be rotated so as to unlock the movement of each of the wheels 12 in succession.

in indicator ma 7 be provided on the drum for showing the operator which of the wheels 12 is free to be operated. This indicator may be of any suitable type. In Fig. 9 I have numbered the teeth of the ratchet. If there are thirty teeth, and consequently thirty units, thirty numbers would be required and there would be thirty cor-- responding holes in the locking drum. A window such as that indicated at w in dotted lines would be provided in the casing, not shown, opposite the number coming at the top, 'wiich shows the unit in position.

the same time by the operation of the drum, a contact maker 77 is operated by means of a second spring controlled blade 78 insulated therefrom and provided with a part which engages ratchet teeth on the (lllllll.

The object of this arran 'ement is to send an impulse to the switching selector at the exhibiting station for bringing the exhibiting unit corresponding to the next setting wheel into the circuit.

ln some cases especially where I use p0- larized magnets for efi'ecting certain of the op-rations l find it convenient to employ an earthing switch 79 which makes contact at each step with a separate stud 8O corresponding with the circuit required to be connected for the operation of the particular indicating unit.

I will now refer to Fig. 10, which, as previously stated, shows a modified form of construction of transmitting wheel, for transmitting single and multiple step impulses.

In this case 81 is the shaft, upon which is mounted, for each transmitter unit, two toothed wheels 82 and 83 the inner wheel 82 being in the present case carried within a recess in the face of the larger one which latter has its teeth out on the outside of a flange.

The teeth on the inner wheel 82 are so proportioned that in a given amount of are there are four such teeth 85 as compared with one tooth 86 on the larger wheel. The

two wheels 82 and 83 are capable of turning independently or" one another excepting so far as this is prevented by the arrangement of pawls hereinaiter described. 87 is an arm pivoted at 81 and provided withtwo pawls. One of these pawls 88 is adapted to engage with the teeth 86 on the wheel 83 and the other pawl 89 is adapted to engage with the teeth 85 on the wheel 82. 90 indicates the outer casing carrying the index letters, and a pointer may be provided in v connection with the arm 87 for indicating which of the letters or other symbols is to be set. 91 is an operating handle.

Mounted within the recess of the larger wheel, and engaging with the teeth 85 on the wheel 82 is a spring controlled pawl 92. This pawl is provided at the back with an no the pawl is liited to operate the contact making blade 94, which makes contact with the screw 95. insulated.

controlled pawl 96 adapted to engage the teeth 86 of: the wheel 83. This pawl 96 is provided with an insulating stud 97 which is adapted, when the pawl 96 is lifted to opcrate the contact making blade 98 and bring the same into contact with the screw 99.

Any suitable means may be provided for preventing the wheels 82 and 83 over running.

The operation of this form of device will be readily understood.

It is first to be observed that the circuit completed by the blade 98 is the multiple step circuit of a selector, which in this case is set forward four teeth at a time, for instance of the type described in my specifications 816730 and 878,064 while the contact blade 9d sends impulses for setting the selector in the exhibiting unit through single step.

In order to render the operation clear, I will consider a specific example.

The arrow 100, at the top of the figure indicates the zero position and it is to be sup- 5 posed that the selector in the exhibiting unit is to be moved through a distance of 10 teeth, in order to set the required indication.

m 1 required setting will be obtained by f two multiple step impulses, each cqui alcnt to four teeth and two single tooth impulses.

The handle 91 is moved into such a position that the pointer mounted on the side of the handle comes opposite the indication on the scale 90, corresponding to the 10th indicatimi. This is the position of the parts on the drawing. p

Vfhen the handle is caused to return, which may be effected in any suitable manner, tor instance by means of a device simiinsulated stud 93 which is adapted when The parts 94: and 95 are suitably Mounted upon the frame is another spring lar to that described in the earlier figures, or by means of a spring and fly governed return, in the first place the pawl 88 moves along the teeth 86, until the forwardend of. the said pawl comes to the back of the next tooth. No motion of the wheel 83 takes place, but in'doin'g' this the pawl 89 being in engagement with a tooth 85 causes the wheel 82 to move through a distance of two teeth thereby sending two impulses at the contact 94 and 95. v

The pawl 88 being now in engagement with the tooth 86, as the motion of the arm 87 continued, the pawl 88 pushes around I the wheel 83 until the zero position is reached, that is in the present case the wheel 83 is pushed forward through a distance of two teeth causing two contacts to be made at the blade 98. i

It is to be observed that as the wheel 82 is mounted within a wheel 83, and held in position by the pawls 89 and 92 and by a device for preventing over running there is no relative motion now between the wheels 83 and, 82, so that no more contacts are made through the blade 94. e I

Although inthe present case I have described an arrangement which is adaptedto send the single step impulses first and then the multiple step impulses to the selector, I may where desirable so modify the arrangement of the parts, that the multiple impulses can be sentv first, and then the single step impulses. 7 7 Y I may also so modify the construction that a series of single impulses can be transmit, ted. In this case I should dispense with the multiple step wheel and contact maker and mount the contact making device 94 and its associated pawl, etc, upon the frame. r 105 Referring now to Fig. 11 this shows [a modified form of the device in which the index 101 is carried by the arm 97 This indexv is seen through a slot inthe casing, and is shown in the zero position ready for set- 1 0 tin II pin is inserted in one of the holes 102, corresponding to the hole 30 in the firstdescribed form of the device. The index carrying member is then pulled around by 5 means of the pin until such pin reaches the zero position indicated by the arrow, when it comes against a stop. At the same time the necessary contacts have of course, been made in the manner already described. The

letter set is now opposite the zero position acting as a record until the index and arm are returned to zero for a fresh setting. This position is determined by the arm 97 being pushed back to the stop 103.

In some cases when I use the index wheels for controlling groups of units having numbers or other indications at the exhibiting station, and it is not required to operate the units in succession at the exhibitlng station 130 I may provide upon the outside of the casing, for instance upon the plate 200 (see Figs. 1 and 4) suitable indlcatlng labels or the like for enabling any particular unit at the exhibiting station to be picked out by the operator and operated from the transmitting station. This arrangement would be particularly useful for cricket scoring and like purposes.

Referring to Fig. 11 which shows a re cording apparatus suitable to be combined with the first form of the transmitting apparatus hereinbefore described.

Mounted on or moving in unison with the setting wheel 2 or the corresponding set part there is a set of type, letters, signs or symbols which correspond to those on the transmltting wheel 12 or scale or corresponding part and to those on the indicating machine. There is a set of type provided for each wheel 12 or the like corresponding to the letters thereon or set thereby. Vhen the transmitting wheel 12 is set in position by the arms 33 and the pins 81 or whatever means may be employeda correspond ng type character is brought into the printing position 151.

The means by which this printing is of fected is now described.

152 is a paper sheet or ribbon which may be fed. from a roll 153 through suitable guides over the platen roller 154 under the spring clips 155, shown by thick lines and mounted on the platen carrier, and between the platen roller 154: and the jockey roller 156 mounted on the spindle 157 the tension of which is controlled by the spring 158. The platen roller 154 and its accompanying parts are mounted on the pivoted arms 159 pivoted at 160 and termed the platen carrier. There being a. suitable distance between the arms 159 corresponding to the length of the platen roller and the width of the paper, the pivots being carried on the frame of the machine, which for clearness is not shown. The paper is fed forward at each operation as hereafter described. 7

Mounted on the arm 159 is a roller 161 which bears on a cam wheel 162, mounted on the shaft 11, as before described in reference to the snail wheel 29. The arm 159 in the position shown is held up against the pull of a spring 16 1 mounted with suitable screw adjustment for regulating the tension on the lug 163 carried by the arm 159 and the pin 165 fixed on the frame. \Vhon the cam wheel 162 is rotated at asuitable time the cut away portion 169 is brought to the roller 161 which thus comes into the position shown by the dotted line 184. Thus the arm 159 is lowered suddenly bringing the platen roller 1541 carrying the paper 152 into a position where it passes the paper on to the inked type at 151 which has been previously inked by the ink roller 168. A further movement of the cam brings the rocking arm 159 back into the normal position shown, and at the same time spaces the paper ready for the next printing.

This is effected as follows Mounted on and behind the end of the lever 159 and revolving about the same center as the platen roller is an arm 170 controlled by a spring 171 attached to a pin on the arm 159. The lever or arm 170 carries pawl 17 2 controlled by a spring 17 3 and engaging with a ratchet wheel 17 1 mounted upon the platen roller. 175 is a pin or lug fixed to the frame and engaging with the arm 170 and when the platen carrier arm 159 is in the position shown this pin 175 causes the arm 1.70 to be rotated forward to its extreme position stretching the spring 171. Vhen the arm 159 lowers the platen as before described on to the type the spring 171 causes the armas it leaves the pin 175 to draw back the arm 170 carrying the pawl 172 backward over the teeth of the ratchet wheel 17 1 thus taking up a fresh spacing so that the ratchet wheel and platen are rotated as the arm 159 is brought back into its normal position. A- pin 176 mounted on the lever platen carrier 159 prevents the ratchet overrunning as the pawl takes up against it at the end of its stroke.

The inking of type is effected as fol lows I Pivoted at 166 are two or more arms 167. These carry at one end an ink roller or set of ink rollers 168 and at the other end each arm has a roller 177 engaging with another cam wheel 178 also mounted on the shaft 11 and turning with it. 179 is a spring which causes the roller 17 7 to be kept against the surface of the cam wheel 178. hen the wheel 178 is rotated so that the cam 180 comes beneath the roller 177, the letter is brought into the position shown by the dotted lines 181 and the ink rollers are brought against the type set at 151. To insure more perfect inking of the type I may provide the shaft of the ink rollers with a friction wheel or pinion shown by the dotted line 182, which when the wheel is lowered comes into engagement with the jockey pulley shown by the dotted line 188 mounted on the frame and rotated by the driving mechanism and which may be hung on a spring arm or have a resilient rim, thus the ink wheels may be momentarily rotated against the'type. The advantage of the above arrangement is that each type is inked as set.

It will be understood by the above de-. scription that the operation is as follows:-

When a printing device is used, the snail 29 is shaped so as to complete the movement of the radial arms 32 to the set position in about half its revolution. The cam wheel parting from the principle.

ing effected by the cam movement, which might be positive in both directions or I could use other means than cams. Gr the ink roller might merely lie on the type in the ordinary manner or be slightly rotated as it is brought from or returned to the next position so as to present afresh surface to the type instead of being rotated as before described.

Referring to Fig. 12 which shows a diagram of connection suitable for controlling a system of units by means of a transmitter of the first mentioned typ I lnthis figure A is the transmitting station and B is the exhibiting station the transmitter in this case is of the type shown in Fig. 1 but embodying the modification shown at Fig. 9; the switch 79,has however two series or contacts instead of one.

Two sources of transmitting current El and S are provided in order to prevent any possibility of short circuiting. It only one source. for instance the source S, were provided it might happen that the position of the last set reversing switch 47 was such that the battery might be short-circuited by the action of the two switches, namely by the reversing switch 47 connected by the brush.

arm 79 to earth and the contact '77, perma nently connected to the same side as the battery. The source S is independent of the other. The setting selector .125 (see Fig; 12 has a spring barrel 120" provided with an escapement 120 operated by the magnet 120. turn in the-direction of the arrow and at each impulse the barrel is turned the distance of one tooth. contact ring 12G engaged by a brush on an arm 1 0 The contact ring has an in'suia tion gap on which the brush rests when the selector isatzero.

The selector being set by the escapement the number of teeth corresponding to the desired letter it is intended to set in the indicating unit, the contact ring has trav'f' eled a corresponding distance under the This allows the current to 7 pass through the motor circuit from the. local supply when the local current is switched on by the completion of the setting cycle of the unit selector 115, which by a short, circuiting plate carried on its arm 117 closes the circuit of a magnetic contact makerthrough contacts and thus closes the supply circuit to all the motors in the units. 7 i

Themotor 121is then driven, the current passing from the positive of the sugoly through the brush on the selector 125 and the ring, thence to the solenoid magnet 1252, and the iield of the motor 121, through the arn'iature (in the direction predetermined by the polarity of the setting current) to the selector magnet 120, having passed through the polarized magnet 118; thence back to the negative of thesupply.

The motor drives the drum carryingthe band or oth rwise controlling the indication carrying memberyrunning in unison with the same is the cam. This cam at each halt revolution comes in contact with the roller on the arm and causes the sprin controlled pawl to rewind the selector 125 one'. tooth. Thus the selector is rewound one tooth for each indication passedy until when the de-. sired indication is reached, the selector has been wound back to Zero. At this moment a stop, not shown. on the selector engages a stop on the frame. A tooth on the ment is cut away,so that it cannot be over- The brush has now broken contact the ring. The current is broken a tie before the drum has reached the corli rect stopping position but the motor circuit, though broken on the selector, is still closed throi W 124' for the locking bolt or catch attached to'the movable core or armature of the magnet 122. w ion the latter is reenergized continues to close the contacts 123 as it rubs'on the drum until the locking catch is able to drop into the slot in the same at the locking The spring barrel tendsto- The selector caries a escapeh the contact 1523, and the resistance position, when the motor which has been slowed up is stopped.

The unit switching selector 115 is operated by the magnet 116, in the same manner as the magnet 120 actuates the selector 125, namely by a spring barrel 115 and an escapement 1.15". The spring of the barrel may be wound up by a solenoid in the main circuit or the supply for the motor, or by a small motor in the parallel circuit; or the selector can be positively driven by the magnet 116, in which case it mak s a complete circle; but I prefer the former arrangement as winding to a stop ant. returning gives security of synchronism.

he operation is as follows The unit locking drum 70 in the transmitting station A is moved one step. This sends an impulse from a second source of supply S through the contact 77 along the line 126 through the magnet 116 returning through the earth to the source of supply. This brings the arm 117 in the switching selector to the second contact stud 123.

The impulses are then sent by means of the transmitting wheel in the transmitter through the contact 17 to the earth through one circuit on to the 79 thence to the earth at the exhibiting station B, through the arm 117 and by the contact stud 128 through the polarized magnet 118, turning it in the direction corresponding with the polarity of the current and operating the switch 119. The current goes through the selector setting magnet 120 returning to the transmitting station by the line 129 through the second circuit on the arm 79 back to the reversing switch 17 and thence to the other pole of the source or supply. In this way the selector at the exhibiting station is set to the required distance and at the same time the switch 119 is thrown over to cause the motor 121 to run in the right direction bringing the next indication into position.

The operation is continued by successively bringing the exhibiting units into circuit as described in my beforementioned previous specifications.

When the arm 11'? is resting on the first and lost contact it brings into operation the rest current from the battery 11 1 at the transmitting station thereby operating the first contact the signal light 112, as the contact 113 is normally closed when the machine is at rest and also the contact 77 (which is not shown at 9 but which is closed when 77 is open) thereby lighting the green lamp 112 and when the contact.

arm 117 reaches the last contact operating the solenoid 110 and lighting the red lamp 111.

The foregoing system shows a method of controlling a number 0t units in which the selectors in the exhibiting station are set in succession, two line wires and an earth being employed for the whole of the units.

In the system shown at Fig. 13 the arrangement is modified in that no unit switching selector is employed at the indi cating station B line wire 130 being employed for each exhibiting unit and the cart-hing switch 131 only havingoneseries of contacts which are connected to the respective reversing switches 1'? of the transmitting unit wheels 12.

W hen the selectors have all been set the current is switched on over the lines 131 and the exhibiting units are set in position.

In a modified system I may dispense with the earthing switch and introduce a line between the points 132 in the transmitting station and 133 in the exhibiting station, a similar connection being provided for each unit. In this case the transmitting machine may be of the type shown at Fig. 1 and the unit selectors are all operated together.

According to a further modification shown at Fig. 1 1 the reversing switches 119 at the exhibiting station may be dispensed with, but in this case the motors 121 must have permanent magnetic fields or be separately excited. V

Referring to Fig. 15 this shows a system in which a hand set transmitter, such as that previously mentioned, is returned to zero electrically by the exhibiting unit as it comes into position.

In this case 134 is the transmitter wheel, having an arm 135 which makes contact on a ring 136, the construction being such that the circuit is broken when the transmitting pointer or the like returns to zero. 17 is the reversing switch, as before described operated by the hand set device as previously described. 118 is the polarized magnet atthe indicating station, the other parts being the same as before, except that in this system there is no unit selector. The contact 137 is closed at each step of the setting of the indicating unit,

The working is as follows:

Supposing the transmitting wheel to be set around through certain distance in the clockwise direction, the reversing switch 17 will be moved in the direction to correspond. The current from the source of supply passes through the switch 17 by the arm 135 through the contact plate 134 and through the line 138 through the locking magnet 122 through the motor field, through the armature of the motor by the reversing switch 119 through the polarized magnet 118, operating the same and back to the transmitting station by the line 139. At each step the contact 137 is closed in unison with the movement of the sign carrying member operating the polarized magnet 140, which returnsfkthe arm or the like 135 one step toward the zero position. This is repeated at each step until when the arm returns .to, zero the circuit is broken. The

. contact 137 is closedat' the commencement of each step ofthe exhibiting unit, thus the indicator will notzhavecompleted its setting -when the circuit: through the, line 138-is broken.

I I The locking ma ,et, however does not breakthe circuit-at the contact 141-11ntil the locking action in, the exhibiting station takes place, as, the-:settimr position, as a described in my. application er. No, 186,207.

It-is to bei observed that. someofthese systems which: have. the magnetic lock 122 upen the"rotatings .drum at the exhibiting unitrcan be. utilized in connection; with a transmitter of thepresent type without the use of selectors yatjthe indicating station, provided thatfthe step bystep motion of the transmitting wheel or; equ valent part is arranged ,to -runslowerlthan the rotation of the'indicator. k V p The-reversingmeans for reversing the,

motor from the control station can also be; used for bringing about'reversalof the inv.dividual unitsyin a system=-where several,

unitsare driven by Ethesamemoton with diiferential gear; as described in my former application, SerialNo. 186,207, last referred to. :In; thiscase the polarized magnet or twoordinary magnets may look ,one or I other-of the difierentialwheels so as to bring about the;;d riying of the unit in-the required direction which being done the selector and a catch. onthe drum may be employed to hold the necessary wheelflocked until the selector: has returned tofzer'o and the last'moyementof the drum or the like is completed.

As has beenpreviously. mentioned atrans 1 vmitting device, of I the kind described in this specification-could be used not only with a selector system but also for working advertising or like apparatus step by step.

I In this case each 'unit setting contactlde- V -gvice "controlled .by 'the apparatus may be connected to, suitable, electric .lock which :;may work in conjuctionwith a separately 1 s w driven unit or may' .be used to lock or unlock aun t movement from a common drive by'diiferential or-othengeanwhich may be friction slip. gear. a q

:In thisway for each contact made by the contact-device the-tmagnetic lock will be released and the, unit-will be thus allowed. to move thedistance of one indication It. will alsobe understoodthat if the in- .dicatingand setting devices are caused to p move. and the movement of the indicating .llnlt be faster than that of the setting device, so that themagnetic lock is always in the locking positionbefore a fresh contact is made by the contact device, the two ,devices will work isochronously or synchronously together. For this purpose the drivngme'ans of the indicating unit is started or switched on first, andawhen. it has at- .tainedthe requisite. speed, the transmitter is started.
